-To all whom it may concern:

Be it known that I, CHARLES ALLEN, a citizen of the United States, residing at El Paso, in the county of El Paso and State of -Texas, have invented new and useful Im tive service, of large capacity, capable of handling all sorts of material, and designed especially for use Where the actuating force may be slight, either because of the slight difference between the. specific gravity of the substances entering the hopper,- or where the substances to be settled consistof very fine slimes.

The invention consists of the parts and the construction and combination ofparts as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which Figure 1 is a vertical section representing the invention. F 2 is a plan of the same in. partial section. Figs. 3, 4, 5, 6 and 7 represent modifications of the invention. Fig. 8 is a cross-section through one of the launder discharges of'Fig. 4. Fig. 9 is a detail of the valve arrangement employed with the lower separator of Fig. 41-. I

A represents a stationary tank of any suit able size and description, adapted to. contain a liquid, such as water, in which the inverted separating cone or receptacle 2 is partially immersed 01' suspended. This cone or receptacle 2 is essentially free to fall and rise in the liquid in the tank A, according as the weight in the receptacle is added to,

- or diminished.

when the cone lifts, by a fixed valve 5 carried by a stem 7 supported in an underneath rigid bracket 8. A flexible connection, such as 9', surrounds the outlet 4 and is secured at one end to a flange 10 which surrounds an opening in the bottom of the tank A, while the upper end of the flexible connection 9 is fastened to the outside of the cone. The purpose of this flexible connection 9 is to prevent the escape of Water from tank A out around the bottom of the cone; and at the same time this flexible connection is or such construction as to prevent its collapsing by reason. ofthe pressure of the water in the tank. to be classified are admitted from any suitable source of supply, as the hopper 11.

In operation, the material to undergo classification, with the Water in which it is suspended, is admitted, as at 11, into the conical receptacle 2; the solids settling. to the bottom of the receptacle, and the water flowing over the edges of the receptacle into the tank A, and thence out, as at 12. The

motive force that actuates the machine is 30 settle to the point of the cone, they accumulate until they cause the cone and'its suspending means to sink; this vertical movement being possible by means of the flexible tube 9. This tube may be of any suitable form, such, for example, as used in trainline pipes and flexible couplings therefor, or in flexible hose used in such an apparatus. As shown, the lower end of the hose is se cured to the end of the flange while the upper end is secured to the lower portion of the separating cone 2. As the cone sinks it opens the sand discharge valve in the bottom of the cone, allowingv the settled solids in the cone to pass out through the outlet 4 until the buoyancy of the ,float 1; over comes the weight of the cone and contents, when the cone'rises, closing the outlet and I valve automatically.

It is to be observed that the settlingcone is freely suspended in the liquid in tank A,

and that the movement of the cone is independent of the means by which it is sus-.

pended or supported. This liquid balance gives a sensitlveness not possible in. ma- I chines using a rigid connection or ordinary 11o fulcruming action.

It is manifest that this dominant ideaofi The pulp stream or sand and water 70 a'cone suspended or partially submerged in a body of liquid and a valved outlet for the cone, is-capable of being embodied in a great variety of forms; and it may undergo various modifications, according to diiferent I conditions under which the invention may bepracticed. Thus, in Fig. 3, the cone 2 is shown as provided with an air tube 13 extendingup into the air chamber to allow the escape of air when water is introduced through the valved pipe ll, whlch latter is adapted to let water into the float to vary its buoyancy. In this Fig. 3 the liqu1d 1s retainediin the tank A by pr'oviding'a suita'bly-packed telescoping connection 9.

It" is desirable for the float to have suiti-v cient buoyancy to hold up the heaviest kind of settling particles accumulated to a depth over theoutlet that will permit them to pass out without much water passing away with themf If the float were adjusted for this work, thcbuoyancy would be too great when treating material'where the settllng particles were light; that is, had very little more specific gravity than water. 'Hence, different floats would have tobe used, or the float be weighted insome manner; and by admitting water to the float the air chamber canbe' easily reduced to the exact point for current froni',

I22. Thence the most perfect work of which the machine is capable, and one float can treat a-llkinds of material. 4

In Fig. 4:, I have shown a pair of these separators arranged in conjunction with 'a launder or pulp sluice 15, the under side of this launder having two discharge tubes 17-18 adapted to deliver solids to the respective suspended cones 2 2.' A jet of water through a pipe 19 is adapted to be directed upward into the tube 17', and a similarojet 20 to beprojected upward through the tube 18. The pulp stream as it flows down the launder passes under a batlle 21,

adjacent to the outlet 17, and such of the materialas is not'heavy enough to'pass downward thr dugh the upwardly ascending beneath a ba'lii o, anc the heavy remaining solid particles fall through .the tube 18 and through the upwardly ascending current of the jet 20, to be deposited in the cone 2;

. the lighter particles and waste'water passa ing on down the launder and over the baflle 24. y In this case I have shown two diflercnt 'methodsof valve control for the cones,2

2t. one instance I suspend the valve 5" I: from above, supporting it on a valvejstem I7, the valve being adapted to .close the' outlet 4 when the cone and its float 3ri se.

" Theoutlet 4: in this instance is shown as a flexible hon-collapsible hose having' its outlet exterior to the tank A, and thus serving "the double purpose as a sand outlet, and also "19 fl as. up over the ballle ses 4 wn the launder'and as aflexible wallto prevent the escape of the" water from tank, A. In the same figure the cone 2 is shown as having a rigid outlet pipe 4 working in a suitable stuffing-box 25, the pipe 4 being open from end to end, but normally closed by contact with a weighted valve plate 5 which is fulcrumed at 26; the

ing the balls or weights 28. These balls run The lower end of the cone has a flexible outs 5 Inthis case, as in the others, the cone is not rigidly supported or fulcrumed, but is free to move up and down in the liquid in the tank A". This submersion, or partial submersion, is of the greatest importance in duced friction and inertia the machine is made sensitive, so that a movement up or down of the cone so as to open or close the valve, results from a slight addition to, or subtraction from, its contents.

In Fig. (3, 2 represents a suspended cone comprising a flexible tube 4: passing horizontally to the outside of the tank A. By this arrangement the valve 5 has its stem l connected loosely with the inner ends of a pair of levers 32 which are fulcrumed, respectivcly, at and the outcrends of the cone descends, so that a slight lowering of the cone creates a large discharge openlng. In the foregoing instances I have shown some c1rcumstances,as in Fig. 7, the desired buoyancy of the separating cone 2 n1ay be 'efliected by the use of a heavy liquldin the Under some circumstances the liquid in the solutions of a specific gravity greater than water, in which case if the fluid in the inner cone is water, the weight of the cone and its of suspension would be needed, the difference between the cone'and'it's contents and the pens1on..

But supposing;- only a certain depth of the iodide of methylone is used and the receptacle then filled with Water. it the proper depth of each solution is used the lowerpart ot' the inner cone will be immersed in the heavier fluid with the upper portion in the water. The inner cone will then be suspended, or float Without any float air chamber, or other means of giving it buoyancy, and will rise and lower with changes in the weight of its contents the same as ifa float were used. Hence a float or air chamber. or other means of suspension, is not necessary in all forms of my machine, While the immersion, or partial immersion, is.
